ARM64: dts: meson-gxbb-wetek-hub: add the ethernet PHY's reset GPIO
This resets the ethernet PHY during boot to get the PHY into a "clean" state. While here also specify the phy-handle of the ethmac node to make the PHY configuration similar to the one we have on GXL devices. This will allow us to specify OF-properties for the PHY itself.
